After having tried to invest in several trees, it became rediculously difficult to reach the 40 ap limit in one tree just so I can take upper tier enhancements. If I took NOTHING out of my racial tree, that leaves me with 42 points spent in one tree. I have a measly 38 points left to distribute amongst two other trees whose action point limits I need to obey in order to pick a few abilities here and there - often forcing me to take things I don't want. This happens because I spent 42 points in one main tree.
Suggestions: This was mentioned in a different thread but I'd like to stress this here:
a) Please lower the pre-requisite AP expenditure in each tree - especially that 40 point one. OR
b) Keep the values the same, but allow the racial tree to count toward the PrE limits in each tree.
For instance, the action points spent in say, kensei, only count toward kensei. The ap's spent in stalwart count toward stalwart. But, the ap's spent in your racial tree count toward the limit in both PrE trees.
That, in my opinion, would be a friendlier system.
